#Go OpenCV binding
|
|
|
|
This is a fork of https://github.com/chai2010/opencv . At the time of the fork (Dec 9, 2013) the original project was inactive, but now it seems to be active again starting from Aug 25, 2014. Efforts to merge the two projects are very welcome.
|
|
|
|
## Install
|
|
|
|
### Linux & Mac OS X
|
|
|
|
Install Go and OpenCV, you might want to install both of them via `apt-get` or `homebrew`.
|
|
|
|
```
|
|
go get github.com/lazywei/go-opencv
|
|
cd ${GoOpenCVRoot}/samples && go run hellocv.go
|
|
```
|
|
|
|
### Windows
|
|
|
|
- Install Go and MinGw
|
|
- install OpenCV-2.4.x to MinGW dir
|
|
- `libopencv*.dll` --> `${MinGWRoot}\bin`
|
|
- `libopencv*.lib` --> `${MinGWRoot}\lib`
|
|
- `include\opencv` --> `${MinGWRoot}\include\opencv`
|
|
- `include\opencv2` --> `${MinGWRoot}\include\opencv2`
|
|
|
|
```
|
|
go get code.google.com/p/go-opencv/trunk/opencv
|
|
cd ${GoOpenCVRoot}/trunk/samples && go run hellocv.go
|
|
```
|
|
|
|
## Example
|
|
|
|
### Resizing
|
|
|
|
```go
|
|
package main
|
|
|
|
import opencv "github.com/lazywei/go-opencv/opencv"
|
|
|
|
func main() {
|
|
filename := "bert.jpg"
|
|
srcImg := opencv.LoadImage(filename)
|
|
if srcImg == nil {
|
|
panic("Loading Image failed")
|
|
}
|
|
defer srcImg.Release()
|
|
resized1 := opencv.Resize(srcImg, 400, 0, 0)
|
|
resized2 := opencv.Resize(srcImg, 300, 500, 0)
|
|
resized3 := opencv.Resize(srcImg, 300, 500, 2)
|
|
opencv.SaveImage("resized1.jpg", resized1, 0)
|
|
opencv.SaveImage("resized2.jpg", resized2, 0)
|
|
opencv.SaveImage("resized3.jpg", resized3, 0)
|
|
}
|
|
```
|
|
|
|
### Webcam
|
|
|
|
Yet another cool example is created by @saratovsource which demos how to use webcam:
|
|
|
|
```
|
|
cd samples
|
|
go run webcam.go
|
|
```
|
|
|
